Ignore any advice to install DirectX 8. In fact, if you're being asked to install dX8, then you're using an extremely outdated installation disc. The x800 card likely requires ATI MMC 9.14 or higher, and the CCC (Catalyst) installer.
I've added these files to this post:

Install these, in this order:
- 10-2_legacy_xp32-64_dd_ccc
- 10-2_legacy_xp32-64_wdm
- 9-14_mmc_uci
- 9-14_mmc_enu
- 9-16_mmc_enu
First one is the Catalyst CCC.
Next is the WDM drivers.
The ATI MMC libraries/misc files to run ATI MMC -- the UCI files.
Finally, install 9.14, then install 9.16 over 9.14. (Note: It may be possible to skip 9.14, but I forget.)
I would imagine this works the same on the x800 card.
